Hello again

I used MSnS-E modification (option 2) with the 1k res. first. Then switched back to the 390 resistor. I checked both R52 and R56 and they are ccw to the click. With the 1k res. the engine just died. With the 390 res. the fuel pump fuse blew.

Well I hope this will help. I will say that this time the engine went lean, died and then the fuse blew (15 amp) for the fuel pump. I did not check the fuel pressure this time, when it died. Usually it stayed at 30 psi., even after it leaned and died. The fuel pressure is 30 psi. at idle, and will g...

I have the same problem, 71 Chevelle small block 383, 29lb. injectors running MS2 ver3 with 2.89. Engine runs fine for about 25 minutes water temp. reaches 175 - 180 degrees AFR set at 14.0 then starts swing between 12.0 to over 16.0 then dies. Let it sit between 15-30 seconds it will restart. I am ...

The gauge in megasquirt (laptop) reads 10:1 and the innovate LC-1 gauge reads 11:1, when the engine is cold. As the engine temp. rises the difference widens, the laptop stays the same and innovate goes up to 12:1. WHICH gauge is correct? I recalibrated the LC-1 in free air. And in Tunerstudio I used...

I was away on vacation for 3 weeks. I will say "its alive - its alive . It is running on the 8 pin. I am starting to tune the fuel and having fun driving the car . Thank you for pointing me in the correct direction.

I was hoping to get a little input on how to get the 5 volts at cranking speed. Like I said earlier,I would like to control all of the timing through MS2. I am not a electronic genius or a computer wizard. I am a old car nut that is moving into some new territory with fuel injection. This has been f...

Sorry for the confusion. I used step 62 to to drive the PWM idle control. I used a tip122 and did not install Q20, D8, and R39. With the power coming from FIDLE terminal on the relay board to the valve and grounded at the engine. And the diode parallel from the power side to ground. I am looking for...

Do I still want to use D8 with resistor in the proto area (for 5 volts), while using the FIDLE for my PWM IAC? If not where should I get power? I am using the relay board. I like the idea of using MS2 for all of the timing including start.

I read and watched the video on the Nova install. My MS2 has step 50 installed. In the video the board must have 5 volts at that location. Mine must need the proto area with the resistor set-up (a little confusion on this step). Since it seems to be remove two jumpers and plug in the two wires (Nova...

I am using the relay board. I jumped from the center to V on the board and also jumped were the relay is mounted. I am running a wire from the board, FIDLE port, to the PWM valve (12 volts). Now the instructions say to put a diode across the PWM, banded end to 12 volt supply non banded to the lead t...
